Mountedupon the mainframe 1 beside and close to the periphery of the turn-table' 2, at about90 degrees removed from the saw-gang and pointing-knives, is the cutoif saw- 16. The face of this saw next to the table is'smooth and unobstructed, as seen in Fig. 2, and the position of the saw is such as to act -upon the projecting end of the bloclr 9 at the base of; the kerfs made by the saw-gang 14, thereby dismembering the groups or clusters of plugs previously made.

Before continuing the description of the machine, it will be well, at this point, to set general operation, after which details of construction and arrangement will be better understood, both as to their nature and objects. Y

Let it be supposed, to begin with, that the swinging frame 13 is raised to its upper limit, so that both the pointing-knives 15 and the saw-gang 14 lie well above the level of the'turn table 2, as seen in Fig. 1. The operator standing by the side of the table remote from the cut-olf saw 1G, now places a block 9 in a cradlev 6, said cradle being at the time in its 'first position, that`is with its open side facing him. In the cradle he clamps the block firmly, by means of the screw 11, the end of the block projecting the required distance to make the predeten mined length of plugs. Theblock being thus clamped and its projecting end further supported up'on the filling piec-8 is now ready to be'operated. upon. The operator then swings thel turntable through an arc sufficient to carry stops it. This is the position shown by the full lines in Fig. 4. The swinging frame 13 now moves down 14 inpassing the block end make a number of pa-ralled kerfs therein to the depth predetermined, that is, the" length of the plugs to be made. The pointing-knives 15 following the saw-gang, on two sides. After the cutting devices have thus acted upon and passed the block, the swingingh frame 13.1noves up again to its first position, the cutting devices returnblock end. Then the operator swings the cradle 6 over to its sec- F 4, thereby turning the block it contains ay quarter round,the turn-table 2 being still stationary. Now. the swinging frame 13 moves dow'n once more, and this time the saws 1l cut kerfs in the block at right angles to the first kerfs, and the pointing knives 15 bevel oli"the other two sides of the plug ends. There is now cut in the a number of square and pointed plugs, which as yet are not severed from the block but, remain as a group or the projecting block into .the path of the cutting devices and theres and the saws of the gang y applied to work bevel off the 'saw-cut sectionsl the dotted lines inA cluster, as seen in Fig. 7. Thereupon the operator swings the turn-table 2 further in its circular path, and `the cutting devices return to their elevated position. "hen the block reaches the .clit-off saw 16 and moves by it, said saw cuts olf thereby dis-membering theroup or cluster, and the separated plugs rop down and are ready for sacking. Meanwhile a repetitiqn of the operation is taking place with :mother block and'so on; and each block is successively adjusted in its cradle until it is used up; andthen a new block is put in the cradle.

It is to be noted that on account of the different positionl in space which the block 9 occupies in its first and second positions, due to the swinging of its cradle on the line of its angle,1it' isnecessary that the length of the saw-gang 14 and the pointing knives 15 be sufiicient toinclude the combined width of both positions, in order to meet the block squarely in both positions. Accordingly, it will be seen in Figs. 2 and 4, and particularly the latter, that the sawgang khas a length morethan double the width of the block; and this is true also of the series of pointing-knives.- Therefore, in the'first position of the block the first half of the cutting devices come into operation, and in the second position the other half are used, as will readily be Seen by reference to Fig. 4.

The saws of the approved type, preferably with inserted teeth, as shown in Fig. 8. The saws are providedl with spacing collars 17 riveted to them and these collars are grooved at 18 to fit a feather 19 on the mandrel 20.

A` feature to be noted is that the grooves 18 in the eyes of the saws are differently located with respect to the circumference in order to throw the teeth of the saws out of line, that is, to stagger them as seen in Fig. 8. This is of advantage in a saw-gang as of the nature herein dethe plugs,

scribed, which requires the saws to be near I together and to operate upon'a relatively small surface, as it prevents too great simultaneous impact pressure.V

The pointing knife device `or head may be of any suitable character, for example. as show'n in Figs. 10-eand 11, wherein the general type ofplaner heads is followed. 21 is the mandrel and22 is the head. The four sides of the 'head are provided with a T-groove 23. and the surface of each side is recessed to receive the pointingfcutting blades 15 which lie therein and are clamped by bolts 24.

Power is led intov the machine through the pulley 25 on the driving shaft 26 mounted upon the foot of main frame 1.

Upon the shaft 26 are two pulleys 27', (Fig. 2) from each of .which a belt 28 passes v1,21e,sae

The counter shaft 31 (if the tightener `pulleys() is mountedI in boxes 33 adapted to 'slide on tracksa on'the main frame l. 35 carryingA suspended4 -weights 36 arie secured to ithevslidable boxes 33 and thus tension is kept on the belts 28.'N By this mechanism the pointing-knives 15 and the saw-gang 14'are'driven.

. which carries a sprocket .44.. Betweenthese sprockets' 42 and 1111 extends an endless chain'y 45, and said chain ata point intermediate a 'thesprockets islfastened to a cross-b'ar13,

of the swinging frame 13; Itjwillgnow" be seen that a reciprocal movement of the chain will-lower and raise the swinging vframe 13. This-movement ofthe chain is imparted to it by means "of a sprocket 46 on the end of the upper shaftA 411, from which sprocket ,a

` chain 47,' as-seen in Figl, passes downto sprocket 48 'on-ashort counter shaft 49 mounted in the frame. This shaft may be operated eithervby hand, as is indicated by the crank 50, or by power, by the followingv means, as best shown in'lig. 2. Upon the counter shaft 419 is kmounted a fast pulley 51. On the shaft, inside this fast .pulleyis a" loose pulley 52 and on said shaft outside said .fast pulley is another loose pulley 53. i

From the inside loose pulley 52 a` crossedbelt 54; leads to a pulley 55 on the-drivingshaft 26,`and from the outside loose pulley 53 a straight belt 56 leads to the pulley '55 on the driving shaft. A'shifting lever'57 as seen in Fig. 3, acts on the crossedbelt 54 blocks 9 i'n lifting them and 4placing them inf .of the swinging frame 13.

In order to counterb, lance the swinging fra-me 13, so that its operation'willbe easy,

. there is a weight 59, as seen in Fig.- 1, suspended from a chain .60 which passes over a sprocket 61 mounted in the top ',of the frame portion1,and down to a vcross-bar 62 In Order to facilitate the hamiiingef the the cradles, there isa hoisting derrick or/ crane comprising a mast63 pvotally mounted" above and below in extensions 64 of the l main framel, so thatlsaidv mast may turn on its axis. rlhc mast carriesa boom 65 from which is properly suspended suitable gripping dogs `66, carried by arunning line? .operated by a w`i'i`1ch68 carried by the mast,
